This node is responsible for recording, persisting, and later providing the actual data for viewing/searching. It is automatically started, if not already running, when a recording session is started, resumed, or viewed/searched. If desired, you can manually start the Event Recorder node ahead of time. It must be running at all times during an ongoing recording session. Once the recording session is paused, you can manually stop the Event Recorder node, if desired. When the last recording session is stopped, the Event Recorder node is automatically stopped.
